Abstract

A physically consistent model is presented for the early-type eclipsing binary system BF Aur, based on a simultaneous solution of its light and radial velocity curves. The less massive fainter (but hotter) secondary is smaller but almost Roche lobe filling component. The system is thus not reverse-algol. The absolute parameters of the system are found to be: M-h = 3.3 M., M-c = 4.1 M., T-h = 15600 K, T-c = 15400 K, R-h = 3.9 R., R-c = 4.1 R.. More accurate radial velocity data are needed before uniqueness can be claimed for the model.
